Key Features
  • Joins solid or standard sector aluminium cable to circular stranded copper cable
  • Friction-welded aluminium-to-copper transition helps minimise electrolysis and galvanic corrosion
  • Designed for 185mm² four-core sector aluminium conductors
  • Factory-filled jointing compound helps protect the aluminium barrel and conductor interface
  • Fully annealed construction including the welded joint
  • Suitable for matched professional crimping tools and dies
  • Single-piece connector supplied individually
Professional Installation Requirements
  • Installation must be performed by a licensed electrician or suitably qualified cable jointer using compatible conductors, approved crimping equipment and the manufacturer's specified crimp sequence. Installation should comply with AS/NZS 3000 and applicable utility or network-owner requirements.
Applications
  • Low-voltage underground residential distribution networks
  • Commercial and industrial switchboard terminations
  • Mains and submains cable connections
  • Utility and infrastructure power distribution
  • Joining large aluminium sector cables to smaller copper conductors
Standards & Compliance
  • AS/NZS 4325 Part 1 for compression connectors and terminals
Environmental Benefits
  • Aluminium and copper components are recyclable at end of service life
  • Friction-welded construction and corrosion-resistant dissimilar-metal transition can extend connection service life and reduce replacement waste
  • Enables the use of aluminium conductors for larger power runs while providing a copper termination interface
  • Jointing compound and treated aluminium reduce corrosion-related premature failures
